Hanuama Bay, a bay located on the south coast of the island of Oahu, is a great place to discover the nature of Hawaii. Hanauma Bay was first discovered by ancient Hawaiians. In 1952, acheologists found remnants of ancient campfires, fishhooks, and other tools. The word Hanauma means curved bay. (Hana=bay, Uma = curve) The bay is a great place to safely learn about hawaiian marine life without harming the marine life.
The bay is huge so Christine, Zack, and I decided on a spot. The spot is in the middle of the bay. The bay also extends very far out so we decided on staying behind this specific wall. Going beyond this wall that is about 100 yards out could be dangerous because of the larger fish, sharks, octupose, etc., and the stronger current. Therefore, we decided to staying inside this wall. Inside the wall there is a huge variety of fish and turtles.

The one fish that I saw throughout the whole bay for what it seemed like constantly was the Convict Tangs. There were so many of them. Although I could not figure or find a specific spot for where they were I did notice that they were always together (never alone). Another fish I saw was the one that blended in with the coral. It was dark and you can hardly spot it but I did a few times. Of course it was always right by the coral camouflaging. It was very dirty, probably so it could blend in with all the coral.
Day #2 Journal (0bservations of Animals)
There were many species that I saw in the waters of Hanuma Bay. When I took observations I swam at a constant slow rate to a marking out about 300 yards out and back in. I swam 2 laps and this is what I saw:
18 Convict Tangs
1 Eel
2 Spotted Puffers
7 Humunukunukus
Spotted Puffer
The Spotted Puffer was always near the coral. It seemed shy and did not travel very much through the coral. It just stayed in one area while I observed it.
Convict Tang
The Convict Tang was never by itself. It was always near another Convict Tang. This may be because they stay near eachother for safety or might be because there are so many Convict Tangs at Hanuma Bay that I could never lose sight of one.
Eel
The Eel was only spotted once by me. I only saw the head poke out of the hole. It did not seem very big.
Day #3 Journal
The temperature of..
shorline water: 77.8 F
15 feet out: 76.0 F
Near rocks: 77.4 F
Water seems to get colder as the water is deeper/farther out.
Air Temperature: 84 F
Water pH(acidity): 7.9
Hypotheses:
If fish feed in the morning, then their food source is more abundant. What is it that makes fish seem more lively in the morning and more abundant in the morning than in the afternoon?
